Some imidazolyl benzamides as potent antibacterial agents

Propolis is a resinous compound produced by honey bees. It contains bioactive molecules that possess a wide range of biological functions. The chemical composition of propolis is affected by various variables, including the vegetation, the season, and the area from which the sample was collected. The aim of this study was to analyze the chemical composition and assess Cerana indica propoli’s antibacterial efficacy from the Kashmir region. Gas chromatography-mass spectrometry (GC-MS) analysis was used to determine the chemical composition of Kashmiri propolis. A range of bacterial strains was tested for antimicrobial activity using different extracts of propolis by agar well diffusion technique. Propolis was found to be rich in alkaloids, saponins, tannins, and resins. The chemical characterization revealed the presence of 68 distinct phytocompounds using GC-MS, and the most predominant compounds were alpha-D-mannopyranoside, methyl, cyclic 2,3:4,6-bis-ethyl boronate (21.17%), followed by hexadecanoic acid, methyl ester (9.91%), and bacteriochlorophyll-c-stearyl (4.41%). The different extracts of propolis showed specific antibacterial efficacy against multidrug-resistant (MDR) strains viz., Pseudomonas aeruginosa (MTCC1688), Escherichiacoli (MTCC443), Klebsiella pneumonia (MTCC19), Cutibacterium acnes (MTCC843), and Staphylococcus aureus (MTCC96). The EEKP showed the highest zone of inhibition against S. aureus (17.33) at 400 µg mL−1. According to the findings of this study, bee propolis contains a variety of secondary metabolites with various pharmacological activities. Furthermore, because of its broad spectrum of positive pharmacological actions and the fact that it is a promising antibacterial agent, more research on propolis is warranted.

Some imidazolyl benzamides as potent antibacterial agents

Abstract: A series of imidazolyl benzamides containing urea has been efficiently synthesized and evaluated for their antibacterial properties. 1 . Some of the molecules exhibited promising antibacterial activity when compared to the reference standard, Ciprofloxacin (Fig. 1).
